Since it was pretty hot already when I started at about 10:00 I decided to ride a real slow pace. The way was straightly to the south where an additional reasonable wind was constantly blowing from. Unfortunately the wind was also very hot and offered no big refreshment.
After about 2 hrs I reached Rüthen which was the first town on the way that can be considered to be within the Sauerland. I took a break there at a bakery where I had lunch and had a little conversation with some locals. They suggested me another route than I had planned. I should go via Brilon. Said, done. The route to Brilon was following a major part of way an old railroad track and was conveniently to ride. A little bit behind Brilon I passed a big, forrest surrounded open air bath - it looked so freshening I really considered to stop the ride and go bathing instead, but I had no swim wear with me and I wanted to reach the Kahler Asten, hence I rode on. But the wrong way. Consulting the map, turning back and looking for the right way - I love that game!
Eventually I was on track to Willingen, which is famous for winter sports and rather high. Unfortunately the initially good looking bike track became worse and was no fun for a road bike. I even had to shoulder it up once when a lumber truck blocked the way. Well, I must say balancing over tree trunks with a bike on the shoulder is quite demanding. The good thing was that this track was going through the forrests and hence a little bit fresher.
When I reached Willingen Upland I again considered to stop there and instead ride the summer bobsleigh run I surpassed on my way and that looked like serious fun. But again I rode on. It was brutally hot now. I really don't know why it seemed that hot. In other years when I cycled the mediterranian coast it was definitly not colder, but this heat was really massive!
A bit after Willingen I lost track again. The map looked promising for a good way to the Kahler Asten, but it was not easy to find it. My gps was of little help only, because I was now in Hessen for which I had no detailed maps on the gps. Eventually I found a way that had the right direction, but instead of a nice little road it was a graveled way for hikers and forrest workers. Anyway I took that way. I wasn't able to ride that way up, too bad underground, serious climb and massive heat. I had to push the bike. When I reached the heights of the Ettelsberg (838m) I really felt close to collapsing, but when I sat in the saddle again (the way was still pretty bad, but at least it was rather flat now) it soon became a bit better. But all in all that hill was a little too much (albeit I tried to go on slowly) which was a pity since it was rather nice up there.
The landscape is a heathland and the views are spectacular. But I valued that not too much instead was more than happy when I reached an asphalt road again. From there I passed the Ruhr spring and quickly went on to Winterberg which I reached much later than originally anticipated. I bought something cold to drink, recovered a moment and went on to the Kahler Asten. The way up there was not too difficult, the climb rather mild.
After 115km I reached the peak and was happy to buy another cold drink. I recovered a while and had a brief chat with another biker who was also pretty much done and wondered why the temperature was that much impacting today. Generally it seemed to be nice up there. Of course it's not the Alps nor the Black Forrest, but today the 842m felt rather like the Mount Everest.
I soon went down to Winterberg again where I had a gorgeous ice cream and then too the way back that I initially had planed. The way back was nice to ride, the way was mildly loosing its heightmeters. Unfortunately the traffic was not too little, but all in al okay.
I reached Bestwig where I decided not to go to Brilon, but directly to Rüthen which included passing another mountain. But before going up again I needed to fill at least one of my water bottles again, strangely it was difficult to find people on the road or in te garden, but eventually I found a lady who gave me fresh water but also remarks that today sporting is dangerous and I would be a fool to do so. Well, I think she was not too wrong, it was indeed too hot, but I kept my slow pace so it was okay. The way up was surprising, because in the middle of the forrest suddenly there are big cranes and huge columns. They are building a new bridge for the Autobahn to Brilon. Very impressing construction site!
Anyway, I reached Rüthen and it became evening already, which was welcome since the temperature lowered a bit. The last 50km were comparatively refreshening and when I reached home after 220 km it was dark already.
All in all it was a nice tour, but a little too hot. It's difficult to keep the pace low enough. The gravel ways in the heathland behind Willingen were a bit too much. Probably it would have been best, if I had decided for the bath in the forrest a little behind Brilon.
